MILK-COOLER'.

SPECIFICATION forming part of Letters (Patent No. 285,773, dated September 2,5, 18.83.

l Application filed March 12, 1883. (No model.)

To @ZZ whom tm/ay concern:

Be it known that I, DANIEL B. Woosrns, of Marshfield, in the county of Washington and State of Vermont, have invented certain new and useful Improvements in Milk-Coolers and I do hereby declare the following to be a full, clear, and exact/description of the invention, such as will enableothers skilled inthe art` to which it pertains to make and use the same.

This invention relates to that class of milkcoolers in which a sheet-metal milk-receptacle is arranged within a cooling-chamber and in contact with a refrigerating medium contained in said chamber. y s

The objects of the improveir ent are to afford a ready inspection of the contents of the milkreceptacle, in o 'rder to ascertain the quantity of cream raised withoutiinterrupting the process of its raising, and to vprovide for a continuous supply of cold Water about the milkreceptacle. 1

The invention consists in certain novel constructions and combinations of parts, which will be hereinafter particularly described, and pointed out inthe appendedclaim.

In the accompanying drawings, Figure 1 is a front elevation of a milk-cooler constructed according to my invention,with the front doors open. Fig. 2 is a vertical section of the same on line x x, Fig. 1. Fig. 8 is ahorizontal section on the line y y, Fig. 1.

The, letter A indicates a cabinet or casing the interior of which is divided into two compartments by a horizontal partition, a, said compartments being provided with doors b and c, respectively. The upper and larger compartment is lined with sheet metal, and is water-tight. Within this upper compartment is arranged a cylindrical sheet-metal milk-receptacle, D, which does not come in contact with the vertical wall of the chamber in which it is arranged, except at the front, and there it is provided with openings d, which coincide with similar openings in the sheet-metal lining of the chamber. The wall of the milk-receptacle andthe sheet-metal lining of the cham- -ber are in contact and soldered together around these openings, and in front of and closing these openings are transparent panes p of glass d d, which permit of the inspection of upper door of the cabinet is open.

When the cooler is in use, the chamber about the milk-receptacle is filled to a proper height with cold water, which surrounds the milkreceptacle, except at the front port-ion, where it is connected with the lining of the inclosing-chamber. It will now beobserved that when the upper door of the cabinet isopen, the glass panes will be fully exposed, and through them will be observed the progress of the raising of the cream upon the milk, and when said door is closed the openingswill be protected, so that the outer air may not, by its contact with the glass panes, affect the temperature of the milk to retard the raising of the cream. The bottom b2 of the milkrecep tacle inclines downward from rear to front, and is not in contact with the bottom of the inclosing-chamber, except at its front portion, where it is soldered to said bottom around openings in both bottoms. From the opening in the bottom of the milk-receptacle a discharge-pipe leads downward through the partition a, and terminates below the same at a proper elevation to permit the placing un-` der it of vessels, into which milk is to be drawn, said spout being provided with a suitable stop-cock. Owing to the inclined position of the bottom of the milk-receptacle, the y milk and cream may flow freely through the dischargeopening even when but little remains to be discharged; and another advantage of this inclined bottom is that the cooling-water flows under and is in contact with it aswell as with the vertical wall of the receptacle. Near the top of the cabinet pipes p p lead through opposite side walls to its interior, a little below the top of the milk-receptacle. To the outer projecting ends of these pipes may be attached hose q q', or other tubing, the one serving to supply Coldwater to the interior of the cabinet, while the other provides for the overflow. Inlay thus constantly renew the water-supply to keep it at a sufficiently low temperature for the most effective creaining of the milk.

The lid A of the cabinet is hinged thereto,

and providedV at its center with a lifting-knob,
